Can someone help me with my question? I don’t understand how to do this.

As we can see by the 60 degree mark at angle C, we know this is a 30-60-90 triangle. I have attached an image of the relationship for a 30-60-90 triangle.

Using the example of y = 1, we can see that x the other leg of the triangle would be y.

So, x is equal to y, which we got from using the relationship shown in the attached image. The correct answer is the fourth option.

Hope this helps! :)

only 10/60 isn't equivalent

hope this : )

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
